Usage Monitoring – Device OTA Upgrade
This section introduces the calculation rule and how to view the data of device OTA upgrades on Developer Center.
Note: A new billing mechanism will be operated on Developer Center from July 2025.
Device OTA Upgrade Description
The package allowance of each device has an OTA upgrade per month, and the maximum limit for a firmware upgrade package to be downloaded per upgrade is 5 MB.
Device OTA Upgrade Calculation Rules:
Firmware upgrade package size during an OTA upgrade / 5 MB. If the result is not an integer, the value is rounded up.
Example:
If the firmware upgrade package during an OTA upgrade of device A is 6 MB, the OTA upgrade attempts consumed is 6/5=1.2, rounded up to 2.
Thus, the device consumes one OTA upgrade in the monthly package allowance and also deducts one OTA upgrade in the top-up package allowance.
Note: If there are no remaining OTA upgrades in top-up package under the account, the device cannot be upgraded due to insufficient OTA upgrades.
Device OTA Upgrade Mechanism
Each device’s monthly OTA upgrade allowance is valid only for the current month.
Once the device reaches the upper limit of OTA upgrade allowance in the given month, no further OTA upgrades can be performed for that month until the allowance resets at 0:00 on the 1st of the next month.
3.If there is a remaining OTA upgrade in top-up package under the account, any OTA usage beyond the monthly allowance will be deducted from the top-up package.
- The device must have sufficient OTA upgrade attempts before an OTA upgrade starts. Otherwise, the device cannot be upgraded.
Example:
For device D123456, on May 1, 2025, it successfully completes an OTA upgrade with a firmware package of 2 MB (counted as 1 upgrade). Until 24::00:00 on May 31, 2025, device D123456 cannot be performed any further OTA upgrades.
From June 1, 2025 00:00, the device will regain 1 OTA upgrade for use during June.
Additionally, if device D123456 had remaining OTA upgrades in top-up package under the account (>0) after its OTA upgrade in May, it could continue using the remaining upgrades in the top-up package until the balance reached 0.
## Remaining OTA Upgrade Attempts in Top-up Packages
This section displays the remaining quantity of device OTA upgrade attempts in top-up packages purchased under the account.
Note:
If the firmware upgrade package size consumed during each device OTA upgrade in a month does not exceed the limit 5 MB but the total number of OTA upgrades exceeds the limit, you need to purchase an OTA top-up package.
If the firmware upgrade package size consumed during a device OTA upgrade exceeds the limit 5 MB, you need to purchase an OTA top-up package.
The resource top-up packages under the account can be used by all devices within the account.
When there are remaining OTA upgrades in top-up packages under the account, the device can perform more than 1 OTA upgrade per month, and the excess usage will be directly deducted from the top-up packages.
When the top-up package balance reaches 0, the device can perform no more than 1 OTA upgrade.
Therefore, if your device has scenarios where the OTA upgrades exceed the package allowance, please make sure to purchase a top-up package in advance to ensure sufficient resources for successful device OTA upgrades.
